Francisella tularensisin Swedish predators and scavengers

Medium-sized exotic prey create novel food webs: the case of predators and scavengers consuming lagomorphs

Food web interactions are key to community structure. The introduction of species can be seen as an uncontrolled experiment of the addition of species. Introduced species lead to multiple changes, frequently threatening the native biodiversity. However, little is known about their direct effect on the upper level of the food web. In this study we review empirical data on the predator-prey relat...

Reduced seasonality in elemental CHN composition of Antarctic marine benthic predators and scavengers

Comparative Transcriptional Analyses of Francisella tularensis and Francisella novicida

Francisella tularensis is composed of a number of subspecies with varied geographic distribution, host ranges, and virulence. In view of these marked differences, comparative functional genomics may elucidate some of the molecular mechanism(s) behind these differences. In this study a shared probe microarray was designed that could be used to compare the transcriptomes of Francisella tularensis...

Comparative review of Francisella tularensis and Francisella novicida

Francisella tularensis is the causative agent of the acute disease tularemia. Due to its extreme infectivity and ability to cause disease upon inhalation, F. tularensis has been classified as a biothreat agent. Two subspecies of F. tularensis, tularensis and holarctica, are responsible for tularemia in humans. In comparison, the closely related species F. novicida very rarely causes human illne...

Learning associations involving predators and non-predators in infancy

Fear is one of the most universal human emotions and many common fears, such as aversions toward predatory animals, has been observed cross-culturally. Previous research has indicated that humans have an evolved predator detection mechanism (Mineka & Ohman, 2002). The present research explored this innate predator detection mechanism in infants by testing whether they are able to learn associat...
